As consumed by me and half London (5)

I believe the answer is:

melon

I'm a little stuck... Click here to teach me more about this clue!

'as consumed by' is the definition.
I can't tell whether this defines the answer.

'me and half london' is the wordplay.
'and' says to put letters next to each other.
'half' means to take half the letters.
'london' with half the letters taken is 'lon'.
'me'+'lon'='MELON'

Can you help me to learn more?

(Other definitions for melon that I've seen before include "Fruit - lemon (anag)" , "US profits" , "Eg, cantaloupe, galia" , "Member of the gourd family" , "Sweet juicy fruit" .)

I've seen this clue in the Evening Standard.
